Seen in the picture here. Taken in probably the 1920s or 1930s. It’s either western Oklahoma or central Arizona. 
I’m hoping the machine type might tell us something.
Thanks, I’m anxious to learn what that might be. I’m just a city slicker. 
It’s hard to tell from here, but this city slicker would guess it’s a mill of some sort.
It looks like an early corn harvester from the turn of the century (1900s or 1910)
It’s hard to get a feel for the scale when you can’t (or I can’t) even tell what’s all part of the the equipment. It looks to me like the wheels in the background are part of something else.
If you do a GIS for antique belt driven corn mill, you’ll get similar pictures. I’m not finding anything exact, or even close enough to get a brand on it yet, but similar enough that it’s the idea that I’m running with right now.
Doing some more searching, I’m still sticking with mill and Sandwich is the brand that seems to have the round hopper.

If you can’t get an answer here, I’m guessing these guys can figure it out.
Thanks for the answers so far. Arizona is not really corn country, but I think OK might be better suited? We grow cotton in AZ, probably not needing anything like this.
